IMPROVED CAR FOR BRICK-DRIERS.

To all whom it may concern- Be' it known that l, GYRUs CHAMBERS, Jr., ofthe city and county of Philadelphia, and State of Pennsylvania, have'invented certain new and useful Improvements in Cars for Brick-Driers;and I do hereby declare the following to be a full and correctdescription of the same, reference being had to the accompanyingdrawings, in which- Figure l is a top view of the car complete.

Figure 2 is a side elevation of the same.

Figure 3 is a side elevation of one of the brick-hold ing slats, orsections.

Figure 4 is a top view of the same.

Figure 5 is an end View of the same.

Figure 6 is lan end View of the ear complete.

Figure 7 is a side and end view of the swinging apron, or air-valve.

The same letter indicates the same part whereverI it occurs.

The nature of this invention consists in a peculiar vconstruction of acar, upon which bricks are intendedto be placed, preparatory to theirpassage through dryingtunnels, whereby easy access is secured for thehacker to every portion ofthe car, for the purpose of loading, and theproper" position of the bricks is so indicated that annuskilledlaborercan readily hack them.'

It further consists in the devices for preventing the heated air frompassing under the car, and for securing a free circulation of air amongthe bricks, all as hereinafter more fully set forth.

To enable others skilled in the art to make use of inyimprovements, Iwill proceed to describe the construction and operation of my improvedcar, referring to the drawings by the letters of reference markedthereon.

The body of the car I form of two side-frames, F F', united together bycross-rods, C; and the fixed endslats S, o1; in any other suitablemanner.

From the upper edges of the side-frames project the slotted eyes e e,Sto., which receive hooks, h h., projecting from the slats S S, 85e.,forming the hinges on which said slats are turned.

An enlarged view of the slats S is seeny in g. 4, a side view, on thesame scale, in iig. 3, and an end view, on the same scale, in iig. 5.

From these, it is apparent that the slats S are formed each of threebars, b b b, united at top by thebrick plates p 157850., placed acrossthem at an inclination, as shown. i

The hooks h h, projecting in opposite directions from one side of eachslat, enter the eyes e e, on the frame, and form, with them, the hingeson which the slats are turned.

The slots in the eyes e e are intended to allow the slats to be foldedon each other, the hook rising in the slot, the thickness ofthe slat,when the latter is folded on to the slat next to it.

The plates P151 make about the size of an ordinary. brick, and theirposition indicates to the hacker the place for each bottom brick, as hebegins the loading of the car.

The object of hinging the slats is to allow them to be folded back, oneon another, as described, so as to afford standing-room between them forthe hacker while engaged in loading the car. Such an open space is seenat X, in figs. 1 and 2.

The wheels W of this car run on rails, R, in a tunnel of heated air.

The axles turn on friction-rollers, o' lr, 85o., attached to rings, heldin brackets B, projecting downward from the car-frame. v

Draw-heads, D, are attached to either end of the car, and serve ashandles to operate them separately, and, when united in a train, allowlateral iiexure sufcient to turn curves.

The car, constructed as hereinbefoie described, is intended, as beforeobserved, -to be drawn through a tunnel, through which a current ofheated air is continually passing from a source of heat at one end, to aflue, or chimney at the other. v

To prevent any considerable portion of this heat from passing beneaththe car, and thus escaping without circulating among the green bricksplaced on the car, I make use of a swinging apron, or valve, V,suspended from the car-flame, and made of such size as nearly to equalin area that of the cross-section ofthe lower portion of the tunnelwhich it is intended to close.

This apron is shown in top View in fig. 1, in end view in fig. 2, infront elevation in g. 6, and in end view and side elevation in fig. 7.

It may be made of sheet-metal, supported by two clamps, or brackets H,suspended, by pivots a, to the car-frame. v

It is weighted at its lower edge, to counteract the effect of strongair-currents upon it, while it is free to swing out of the Way of anyobstruction it may encounter.

The axles of the car are placed suiiciently near the ends of the car toprevent it from tilting, when loaded at one end only, and yet nearenough to each other to allow of the easy turning of curves.

Having thus fully described my invention,

. What I claim therein, and desire to secure by Letters Patent, is

l. The bottom of the car, constructed of the hinged slats S S, 85e.,capable of being turned over on to each other, in the manner and for thepurpose described.

2. The slatsS, constructed in the manner herein specified.

3. The swinging apron V, constructed and suspended substantially as andfor the purpose described. The above specication of my said inventionsigned and witnessed at Boston, this 15th day of August, A. D. 1868.
